No definitely didn't have 150 you're right - I put 2 in the cart Tuesday night when I ordered that KCenter Exclusive just to see what they had....it said only 1 was currently available. When I put my order thru & paid, I went back to the page about three minutes later just to see and it was already listed as "discontinued." I think they seriously only had 1, the 1 that I got because I ordered it literally within minutes of their posting it in an announcement.
KCenter has a really bad problem with having only 1 or 2 of things though. I was telling Bobby yesterday, even other items that are hard to find, I try to add 2 to the cart and I get 1 right away and if I'm lucky enough to get the 2nd one at all, it takes about a month to get it direct from manufacturer to KCenter then to me.
